Abstract: 917,341. Artificial heart valves. EDWARDS, M. L. Aug. 8, 1961 [Aug. 11, 1960; April 24, 1961], No. 28615/61. Class 81 (2). [Also in Group XXIX] An artificial valve for a heart, comprising a base ring and a valve member, has a flexible annular pad around the base ring by means of which the valve may be sewn into position. The base ring is built up from a flanged outer portion 129 and an inner ring to which a ball-retaining cage 111 is attached, the two being so shaped as to provide a groove 113 in which the fabric sewing ring 115 is secured by wire 117, around a clamping ring 116, and stitching 120. In the form shown, the ball 112 engages against a seating 127 on a synthetic rubber member 125 which also provides an annular shield 130 to engage the walls of the artery and prevent clots, resulting from the stitching operation, from passing into the blood stream. However, in another form, there is no shield and the ball seating is formed directly on the inner face of the base ring. The body portions may be made of stainless steel but preferably they and the ball are made of acrylic resin. The sewing ring is made from knitted synthetic fibre fabric since the natural tissue grows into the interstices of this and securely retains the valve after the sutures have been dissolved.

Title: Improvements in transmission systems, more particularly for vehicles
IPC: F16H45/00
Filed: 1953-10-16
Abstract: 753,512. Hydraulic transmission of power. EBERT, H. Oct. 16, 1953 [Oct. 18, 1952], No. 28660/53. Class 69 (2). An hydraulic transmission for vehicles comprises an hydrodynamic clutch in series with an hydrostatic infinitely variable gear. An impeller 5 of a Fottinger type clutch is integral with a driving-shaft 1, a driven member 6 being integral with a shaft 7. The shaft 7 drives a cylinder block 19 of a swash-plate type pump directly, and, through gears 20, 22, 23, 24 and a shaft 18 drives a cylinder block 29 of a second swash-plate type pump. Communication between the cylinders of the two pumps is permitted through kidney ports 35 in a control disc 34 which is fixed to a casing 51, 52 to which the output shaft 40 is secured. If the swash-plates are adjusted to give a maximum stroke to the pistons 45 of the first pump and zero stroke to the pistons 45<SP>1</SP> of the second pump, the shaft 7 is directly coupled to the output shaft 40. If the swash-plates are adjusted for maximum stroke of pistons 45<SP>1</SP> and zero stroke of pistons 45, the output shaft is coupled to shaft 18 and runs at reduced speed relative to shaft 7 due to reduction gearing 20, 22, 23, 24. The hydrostatic gearing is infinitely variable between these two limits. On starting the output shaft 40 is coupled to the shaft 7 through the reduction gearing, and just prior to that point at which a change in the reduction ratio of the hydrostatic gearing is necessary to prevent an increase in engine speed, the driving shaft 1 is clutched to shaft 7 by a disc clutch 10, 11, 12 engaged by means of a centrifugal pressure-operated control which is dependent upon the speed of the output side of the system.
